The documentation for external sorting / partial lists uses incorrect parameter 
name which could allow users to believe the functionality does not work.

                 Key: DISPL-455
                 URL: http://jira.codehaus.org/browse/DISPL-455
             Project: DisplayTag
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 1.1
            Reporter: Rick Smith
            Priority: Minor


The documentation for external sorting / partial lists indicates the following 
line of code should be used to determine the specific page that the displaytag 
has passed back to the request:

To determine the starting record you need to return based on the request 
parameters provided via Display Tag you can do:

(Integer.parseInt(request.getParameter((new 
ParamEncoder(tableId).encodeParameterName(TableTagParameters.PARAMETER_ORDER))))
 - 1) * pageSize

I believe the correct parameter should be: 

(Integer.parseInt(request.getParameter((new 
ParamEncoder(tableId).encodeParameterName(TableTagParameters.PARAMETER_PAGE)))) 
- 1) * pageSize
